Prasad cautioned against a common reaction among parents to say, "Well, that defines a regular teenager."

“If you start to see these behaviors going on for at least two weeks or longer, and then it’s interrupting their ability to function at home or school, that’s when you might need to get some help,” Prasad said.

Research shows up to 20 percent of teenagers will experience depression before adulthood. Fifty-one percent of teens are afraid to talk to their parents about personal problems.

“Every time I do say something, it goes through one ear and out the other,” said 13-year-old Jordan Haggard.

Oldham said she feared upsetting her parents by sharing her problems.

“I don’t want to tell them, ‘Hey, I’m feeling depressed, I have really bad anxiety right now,’ because they may feel like ‘Well, what am I doing wrong?’” Oldham said.

Oldham shared her video diary with her mom, Courtney Meyer.

“You should never worry about it making me feel bad because I’m here to help you,” Meyer told her daughter. “If it’s something that I can help you with I want to do that.”

Many teens also expressed a deep fear of meeting their parents’ expectations — the pressure to perform.

“Forget sleep, forget having a social life,” said Payton Campbell, 17. “I constantly find myself working and over-extending myself.”

Nazarene Freeman, 17, said the push to “always do this and that” is constant, and one that is difficult to talk about with parents.

“The expectations are so high that when you jump for that ...you’re afraid you’re going to fall,” Freeman said.

Nazarene’s father Stephen also watched his child’s video diary.

“For me, I’m sorry about (the) pressure,” Freeman said. “But I’m going to always be proud of you no matter what you do because you’re my kid. That’s enough. I’ll always love you because you’re mine.”
